Software M1 Max MacBook Pro Resolution Workaround

Product Information

The M1 Max and M1 Pro MacBook Pro laptops have a limitation in their native screen resolution, which prevents users from changing to lower 16:10 resolutions such as 1280×800 and 1600×1000. This limitation restricts the resolution to 1920×1200, resulting in smaller text. Apple is aware of this issue and actively working on a patch to resolve it. In the meantime, a 3rd party solution called SwitchResX can be used to adjust screen resolution options.

INTRODUCTION

We are aware of the current native screen resolution limitations on the new M1 Max and M1 Pro MacBook Pro laptops that affect your ability to change to a lower 16:10 resolution such as 1280×800 and 1600×1000, thus limiting your resolution to 1920×1200 (aka – rather small text).
